Neutral zone

For modulating actuators, note the control characteristic for the selected switch-on point
of the setpoint. The diagram shows the setting characteristics by including the neutral
zone for range DC 0...10 V.
The diagram shows the setting characteristics by including the neutral zone. The values
for the neutral zone listed in the diagram apply to DC 0...10 V (without characteristic
function).

Hysteresis
H = 70 mV
Neutral zone NZ = 200 mV
The diagram shows the relationship between the differential voltage E = Y – U
(difference between setpoint Y and actual value U) and the direction rotation, including
hysteresis and neutral zone.
For DC 0...35 V (with characteristic function) the following values apply:
Neutral zone NZ = 2 % of span
Hysteresis H = 0.7 % of span
